Definitions

  • the invention relates to a device for separating water by means of gravity segregation from water insoluble substances contained therein, comprising a reservoir having a mixture supply, a water discharge and at least one discharge for separated substances which is separate from said water discharge, at least one flow path being established in the reservoir, in which a plurality of flat separation channels and a supply chamber and a discharge chamber communicating with said separation channels are arranged, said separation channels being vertically piled up in parallel relationship and bounded by channel walls.
  • Such a device is known.
  • the inlets of the separation channels piled above each other join a large supply chamber, so that the disadvantage occurs that the large particles of light substances may rise in the supply chamber and the large particles of heavy substances may descend in said chamber, as a result of which the upper separation channels have to work up proportionally too many light substances and the lower separation channels have to work up proportionally to many heavy substances.
  • the invention has for its object to divide the substances better over the separation channels.
  • FIGS. 1, 3, 5, 7, 8, 11 and 12 each a longitudinal sectional view of a preferred embodiment of a device in accordance with the invention
  • FIG. 2 an elevational view taken on the line II-II in FIG. 1,
  • FIG. 4 an elevational view taken on the line IV-IV in FIG. 3,
  • FIG. 6 an elevational view taken on the line VI-VI in FIG. 5,
  • FIG. 9 a plan view of a variant of detail IX of FIG. 8, and
  • FIG. 10 a sectional view taken on the line X-X in FIG. 9.
  • the pile 19 of separation channels 6 is arranged between a feeding chamber 20 and a delivery chamber 21 of the reservoir 4.
  • a flow way according to arrows 27 and 81 is established in the reservoir 4, wherein the separation channels 6 and the feeding chamber 20 and the delivery chamber 21 communicating with said channels 6 are incorporated.
  • that liquid which flows in said path is constrained to flow through said channels and is divided by the vertically spaced inlet mouths defined thereby so that each channel receives a portion of the liquid flow.
  • a mixture 5 of water 2 and substances 3 is passed in the direction of the arrow 27 through the plurality of separation channels 6 with such a low speed that by gravity the substances 3 are urged against the lower sides of the separation walls 7, along which they are moved in the direction of the arrow 27.
  • the substances 3 are joined by the guide members 25 to narrow streams, which enter the delivery chamber 21, where they rise in the form of ascending drop streams 26 into the collecting space 17.
  • the substance outlet 12 is turned about an axis 29, for example, by manually actuating a lever 30, for tapping the substances 3.
  • the purified water 2 flows through the overflow 14 towards the water outlet 16.
  • the teeth 24 are spaced apart at their top ends at a small distance from the separation channels 6. They form part of a comb 22.
  • the device 46 shown in FIG. 7 comprises a reservoir 4 having a mixture inlet 8 on the bottom side and separation channels 6 whose inlets 47 are arranged in superposition and communicate with a standing feeding chamber 49 converging in the direction of flow 48 in order to ensure that the separation channels 6 all receive equal quantities of substances 3.
  • the readily separated substances for example, light oil, arrives at the inclined wall 50 and flows therealong into the collecting space 17, which is arranged at a high level in the reservoir 4.
  • the inclined wall 50 forms displacer or flow distributor means distributing a mixture 5 among the separation channels 6 in the vertical direction 23, in that the inlet to the flow path through the channels from the feeding chamber 49 is increasingly restricted by the wall 50 in upward direction, that is to say in the segregation direction.
  • the heavy substances 38 collected in the spaces 39 and 55 are removed through outlets 43 and 56.
  • the device 68 shown in FIG. 12 differs from device 64 in that the separation channels 6 are inclined away from the central feeding chamber 49 in an upward and outward direction and in that substance guide members 25 are arranged on the outer walls of the separation walls 7.
  • the mixture 5 and the substances 3 then flow in the same direction 27 through the separation channels 6.
  • Large particles of light substance 3 may rise along the displacer 53 and through a tube 86 reaching into the collecting space 17, whereas the mixture is urged through the separation channels 6 towards the delivery chamber 21.
